ABSTRACT:
A low cost sensor is described. The sensor is responsive to the component of a force applied to the sensor relative to an axis of the sensor. The sensor comprises rigid, spaced-apart support members. At least one pair of electrically-conductive elements are positioned to move with the support members in response to the force, contact and compress against one another as the force component varies relative to the axis such that the electrical impedance between the two elements changes as said component of force changes.
